Sensor data set of 3 electromechanical cylinder at ZeMA testbed (2kHz)

General information on the data set

The data set was generated at the ZeMA testbed. A working cycle lasts 2.8s and consists of a forward stroke, a waiting time and a return stroke. The data set does not consist of the entire working cycles. Only one second of the return stroke of each working cycle is used.

Structure of the data

• data saved in three HDF5 file as a 3D-matrix, one file is for one axis
• one row represents one second of the return stroke of one working cycle
  axis 3: 6292 cycles
  axis 5: 6083 cycles
  axis 7: 5732 cycles
• one column represents one datapoint of the cycle, that is resampled to 2 kHz (2000 columns)
• one page represent one sensor (11 pages: 11 sensors)
